Playstation 2 controller to PSP adapter

[TokyoDrift] built an adapter that allows you to connect a PlayStation 2 controller to a PlayStation Portable. It’s a bit different from similar hacks as this adapter doesn’t require any hardware alteration to the PSP or the controller. To do so, a plug-in is used on the PSP firmware side of things. The adapter then makes use of video out and PS2 controller extension cables, along with an ATmega8 microcontroller to handle the signals between the two devices. We posted a picture of the guts because we like that king of thing but the finished project is nicely housed inside of a project box. See for yourself in the video after the break.

@Frogz: yes L2 and R2 buttons are supported of course
due to the bad quality of my ps2 pad (5$ ebay thing) those don’t work very well, that’s why I didn’t include that feature in the PSP plugin
the buttons could be useable with like 4 more lines of code though

@Scott: actually it works quite well
the serial port is fast enough, i mean the PSP is limited to 60 frames per second anyway, so I don’t have to transmit too much data through the port
the plugin does not take too much power, too, and if it does you can clock the PSP’s CPU up to 333MHz (normal is 222MHz)
this is no overclocking, 333MHz is within the specifications
